Ok im seeing Total/Valid blocks 1 / 1 now. So I found a block?
Still no change in wallet balance though, maybe it takes a while to update?
Edit: i'm using Claymore solo edition wallet but in readme it now says: 1. Use official Primecoin wallet with this miner. Should I switch?
no, you use claymore wallet
the part about the official primecoin wallet is you need an official primecoin wallet so claymore can connect to the actual wallet data file
check your immature coins. if you've found a block you should see 7.686 XPM in there. this takes 3200 confirmations to be usable.
to find out how many you've got, just hover over the recent transaction that has two hammers.
Start miner and see what messages it shows at starting, it will tell you what wallet you should use. v3.0 required custom wallet. Version v3.0b and newer requires standard official wallet.
